The Scheule refen'e to these Letters Patent and making part of the same.

To all wlwm tt 'nuty coacern Be it known that I, MICHAEL WALPoLn, of-Milford, in the county of Worcester and State of Massachusetts, haveinvented certain new and useful Improvements in l"ulc1'nm-Pince1's forBoot and Shoe- Makers; and I do hereby declare that the following is afull, clear, and exaot description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereonwhiohorm a part of this specification.

My invention relates to and is intended as an improvement upon thefulerum'pincers for which Letters 1 atent were granted to nie; andconsists in the construction and mode of adjnsting the fulorurn, as willbe hereinafter fully set forth. In order to enable others skilled in theart to which my invention appertains to make and use the same,I will nowproceed 'to desoribe its construction and operation, .referring to theannexed drawing, in whichignre 1 is a side view, and

Figure 2 is a front view 'of my improved pinoers.

A represents the upper, and

B, the lower jaw, constructed with their respective handles O and D inthe same manner as described in my former patent, above referred to.

The handle O is slotted for a suitable distance below the jaw A, for theinsertion and pivot-ing of the lower jaw B in the upper end, and for thefulcrum E to move up and down.

At the lower end, on each side of said slot in the liandle G, are formedratohet-teeth a a, on the front side' The fnlcrnmE has, at its inner endor base, a downward-extending projection, b, which is, on its inner 'nnshead isteveiea on the side towm'd the sioaed handle, as shown in fig. 1,and a spring, is secured to the back thereof, which spring extendsdownward and bears against the inner side of the haudle.

By the means of this spring the fulcrum E is held firmly at any pointwhere it maybe set, and it is moved by an upward pressure on thefulcrnm, which releases the teeth on the projection b from the ratohetteeth a a, the beveling of the head d allowing or rendering thismovement possible.

Having thns fully described'my invention,

What I clairn as new, and deslre to secure. by Letters Patent, is-- p 1.The slotted hanclle C, provided with ratohet-teeth (w on each side ofthe slot,substantially as .and for the purposes heiein set forth.

2. The fulcruni E, provided with toothed projections b, tenon e, head d,and spring j, all oonstrnoted` and arranged to operate substantially asand for the par-g poses herein set forth.

3. The combination of the jaws A B, handlesO D, teeth a a, fnlcrnm E,projection b, tenon e, head d, and spring f, all constructed andarranged as descrihed, to operate substantially as and for the purposesherein set forth. I

In testirnony that I olaim the foregoing as my own I atfix my signaturein presence of two wituesses.
